DM-Apollyon's Tear

Mount Apollyon: The largest active volcano on the tiny planet of Nafs-Amara, located in the M45 star cluster. The study of its subterranian magma, dubbed "Apollyon's Tear," is of such great scientific value that research facility NAAT-1 was built around and inside the volcano itself. This facility has been specially designed to sustain regular floodings from magmatic activity. Between eruptions, while the scientists are on vacation, NAAT-1 rents out their space for tournaments!
